Late response, I was out of town.
I had heard that one way to check for a blown and or leaky head gasket, is to put compressed air into the cylinder and hand crank the engine a full cycle. If you get bubbles, from the compressed air, into the expansion tank....you have problems.
So I hooked up the compression tester to cylinder one. Instead of attaching the pressure gauge, I attached a line from my shop air compressor and pressurized to 120psi. I then hand cranked the engine to check if air was escaping from the cylinder into the coolant system. I repeated the process on cylinder 2,3 and 4.
Hope that is a better explanation.
Moving forward, the new expansion tank cap and thermostat is installed along with a new belt tensioner (old one was shot). Today is play with the car again day so fingers crossed. Ill update appropriately.
